大学的每个专业都要编制教学计划。假设任何专业都有固定的学习年限，每学年含两学期，每学期的时间长度和学分上限都相等。每个专业开设的课程都是确定的，而且课程的开设时间的安排必须满足先修关系。每个课程的先修关系都是确定的，可以有任意多门，也可以没有。每一门课程恰好一个学期。试在这样的情况下设置一个教学计划编制程序。三、基本要求：（1）：输入参数：学期总数，一学期的学分上限，每门课的课程号，学分，直接先修关系的课程号。（2）：课程号尽可能的集中在前几个学期中。（3）：若无解，则报告错误信息；否则见教学计划输入到指定的文件中。计划的表格格式自行设计-University of each professional should prepare teaching plans. The assumption that any professional have fixed the length of each school year with two semesters each semester and the length of time equal to the credit limit are. Every professional courses are opened to determine, and the creation of curriculum time arrangements must meet pre relations. Each course is the pre-established relationship, can have any more doors, there will be no. Each course just one semester. Tests in the circumstances set up a teaching program procedures. Three basic requirements : (1) : input parameters : total semester, a semester"s credit ceiling for each class courses, credits, direct relationship prevocational courses,. (2) : N

栈(stack)是程序设计过程中经常遇到朝气一种数据结构形式，它对于数据的存放和操作有下面这样的特点： 1) 它只有一个对数据进行存入和取出的端口； 2) 后进者先出，即最后被存入的数据将首先被取出。其形式很象一种存储硬币的小容器，每次只可以从顶端压入一个硬币，而取出也只可以从顶端进行，即后进先出。 这样的数据存储和管理形式在一些程序设计中很有用。例如，编译系统中(这是一类比较复杂的程序)，对于函数调用的处理、对于表达式计算的处理，都利用了栈这样的数据结构。- The stack (stack) is in the programming process frequently meets the vitality one kind of construction of data form under, it has such characteristic regarding data depositing and the operation: 1) it only has a logarithm according to the port which carries on stores and takes out; 2) less advanced first leaves, namely finally the data which will store first is taken out. Its form looks like one kind of memory coin very much the small container, each time only may press in a coin from the peak, but takes out also only may carry on from the peak, namely less advanced first leaves. Such data storage and the management form are very useful in some programmings. For example, in the compiling system (this is a kind of quite complex procedure), transfe
